AAT3157
High Efficiency 1X/1.5X/2X Charge Pump for White LED Applications
General Description
Features
The AAT3157 is a low noise, constant frequency charge
pump DC/DC converter that uses a tri-mode load switch
(1X), fractional (1.5X), and doubling (2X) conversion to
maximize efficiency for white LED applications. The
AAT3157 is capable of driving up to three channels of
LEDs at 20mA per channel from a 2.7V to 5.5V input.
The current sinks may be operated individually or in parallel for driving higher current LEDs. A low external parts
count (two 1µF flying capacitors and two small 1µF
capacitors at IN and OUTCP) make this part ideally
suited for small, battery-powered applications.
•VIN Range: 2.7V to 5.5V
• Fully Programmable Current with Single Wire
▪ 16 Current Levels
▪ Four Low Current Settings Down to 50µA
• Low IQ (50µA) for Low Current Mode
• Tri-Mode 1X, 1.5X, and 2X Charge Pump for Maximum
Efficiency and VF Coverage
• Drives up to Three Channels of LEDs
• No Inductors, Low Noise Operation
• 1MHz Constant Switching Frequency
• Small Application Circuit
• Built-In Thermal Protection
• Automatic Soft Start
•IQ <1µA in Shutdown

Skyworks' S2Cwire™ (Simple Serial Control) serial digital
input is used to enable, disable, and set current for each
LED with 16 settings down to 50µA. The low-current
mode supply current can be as low as 50µA to save
power.
Applications
Each output of the AAT3157 is equipped with built-in
protection for output short-circuit and auto-disable for
load short-circuit conditions. Built-in soft-start circuitry
prevents excessive inrush current during start-up. A lowcurrent shutdown feature disconnects the load from the
input and reduces quiescent current to less than 1µA.
• Color (RGB) Lighting
• Programmable Current Sinks
• White LED Backlighting
• White Photo Flash for Digital Still Cameras

Functional Description
The AAT3157 is a tri-mode load switch (1X) and high
efficiency (1.5X or 2X) charge pump device intended for
white LED backlight applications. To maximize power
conversion efficiency, an internal sensing circuit monitors the voltage required on each constant current sink
input and sets the load switch and charge pump modes
based on the input battery voltage and the current sink
input voltage. As the battery discharges over time, the
AAT3157 charge pump is enabled when any of the three
current sink inputs nears dropout. The charge pump initially starts in 1.5X mode. If the charge pump output
droops enough for any current source output to become
close to dropout, the charge pump will automatically
transition to 2X mode. The AAT3157 requires only four
external components: two 1µF ceramic capacitors for the
charge pump flying capacitors (C1 and C2), one 1µF
ceramic input capacitor (CIN), and one 0.33µF to 1µF
ceramic charge pump output capacitor (COUT).
The three constant current sink inputs (D1 to D3) can
drive three individual LEDs with a maximum current of
20mA each. The unused sink inputs must be connected
8
to OUTCP, otherwise the part will operate only in 2X
charge pump mode. The S2Cwire serial interface enables
the AAT3157 and sets the current sink magnitudes.
Constant Current Output Level Settings
The constant current sink levels for D1 to D3 are set via
the serial interface according to a logarithmic scale for
the first 12 codes and a separate low-current scale for
the last four codes. For the first 12 codes, each code is
approximately 1.5dB lower than the previous code. In
this manner, LED brightness appears linear with each
increasing code count. Because the inputs D1 to D3 are
true independent constant current sinks, the voltage
observed on any single given input will be determined by
the actual forward voltage (VF) for the LED being driven.
Since the input current sinks of the AAT3157 are programmable, no PWM (pulse width modulation) or additional control circuitry is needed to control LED brightness. This feature greatly reduces the burden on a microcontroller or system IC to manage LED or display brightness, allowing the user to “set it and forget it.” With its
high-speed serial interface (1MHz data rate), the input

is held high to latch the data. Once EN/SET has been
held in the logic high state for time TLAT, the programmed current becomes active and the internal data
register is reset to zero. For subsequent current level
programming, the number of rising edges corresponding
to the desired code must be entered on the EN/SET pin.
S2Cwire Serial Interface
When EN/SET is held low for an amount of time greater
than TOFF, the AAT3157 enters into shutdown mode and
draws less than 1µA from VIN. The internal data register
is reset to zero during shutdown.
The current level magnitude is controlled by Skyworks'
Simple Serial Control (S2Cwire) serial interface. The
interface records rising edges of the EN/SET pin and
decodes them into 16 different states. The 16 current
level settings available are indicated in Table 1.

Auto-Disable Feature
The AAT3157 is equipped with an auto-disable feature for
each LED channel. After the IC is enabled and started up,
a test current of 100µA (typical) is forced through each
sink channel. The channel will be disabled if the voltage
of that particular SINK pin does not drop to certain
threshold. This feature is very convenient for disabling an
unused channel or during an LED fail-short event.
Thermal Protection
Table 1: Current Level Settings.
The AAT3157 has a thermal protection circuit that will
shut down the charge pump if the die temperature rises
above the thermal limit, as would be the case during a
short circuit of the OUTCP pin.
The S2Cwire serial interface has flexible timing. Data can
be clocked-in at speeds greater than 1MHz, or much
slower, such as 15kHz. After data is submitted, EN/SET

DATA SHEET
AAT3157
High Efficiency 1X/1.5X/2X Charge Pump for White LED Applications
Applications Information
Capacitor Characteristics
Although the AAT3157 is designed for driving white LEDs,
the device also can be used to drive most types of LEDs
with forward voltage specifications ranging from 2.0V to
4.7V. LED applications may include main and sub-LCD
display backlighting, camera photo-flash applications,
color (RGB) LEDs, infrared (IR) diodes for remotes, and
other loads benefiting from a controlled output current
generated from a varying input voltage. Since the D1 to
D3 input current sinks are matched with negligible voltage dependence, the LED brightness will be matched
regardless of the specific LED forward voltage (VF) levels.
In some instances (e.g., in high luminous output applications such as photo flash), it may be necessary to drive
high-VF type LEDs. The low dropout current sinks in the
AAT3157 make it capable of driving LEDs with forward
voltages as high as 4.7V at full current from an input supply as low as 3.0V. Outputs can be paralleled to drive
high-current LEDs without complication.
Ceramic composition capacitors are highly recommended over all other types of capacitors for use with the
AAT3157. Ceramic capacitors offer many advantages
over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low ESR, is
lowest cost, has a smaller PCB footprint, and is nonpolarized. Low ESR ceramic capacitors help to maximize
charge pump transient response. Since ceramic capacitors are non-polarized, they are not prone to incorrect
connection damage.
Device Switching Noise Performance
The AAT3157 operates at a fixed frequency of approximately 1MHz to control noise and limit harmonics that
can interfere with the RF operation of cellular telephone
handsets or other communication devices. Back-injected
noise appearing on the input pin of the charge pump is
20mV peak-to-peak, typically ten times less than inductor-based DC/DC boost converter white LED backlight
solutions. The AAT3157 soft-start feature prevents noise
transient effects associated with inrush currents during
start-up of the charge pump circuit.
Capacitor Selection
Careful selection of the four external capacitors CIN, C1,
C2, and COUT is important because they will affect turn-on
time, output ripple, and transient performance. Optimum
performance will be obtained when low Equivalent Series
Resistance (ESR) ceramic capacitors are used. In general, low ESR may be defined as less than 100mW. A value
of 1µF for all four capacitors is a good starting point when
choosing capacitors. If the LED current sources are programmed only for light current levels, then the capacitor
size may be decreased.
10
Equivalent Series Resistance
ESR is an important characteristic to consider when
selecting a capacitor. ESR is a resistance internal to a
capacitor that is caused by the leads, internal connections, size or area, material composition, and ambient
temperature. Capacitor ESR is typically measured in milliohms for ceramic capacitors and can range to more
than several ohms for tantalum or aluminum electrolytic
capacitors.
Ceramic Capacitor Materials
Ceramic capacitors less than 0.1µF are typically made
from NPO or C0G materials. NPO and C0G materials generally have tight tolerance and are very stable over temperature. Larger capacitor values are usually composed
of X7R, X5R, Z5U, or Y5V dielectric materials. Large
ceramic capacitors (i.e., greater than 2.2µF) are often
available in low-cost Y5V and Z5U dielectrics, but capacitors greater than 1µF are not typically required for
AAT3157 applications.
Capacitor area is another contributor to ESR. Capacitors
that are physically large will have a lower ESR when
compared to an equivalent material smaller capacitor.
These larger devices can improve circuit transient
response when compared to an equal value capacitor in
a smaller package size.
